Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 5 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 251 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

contexts scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Project Context Files (contexts/)

  1. Context files in contexts/ provide detailed project documentation for agents with zero context.
  2. Read relevant context file before working on a project (e.g., contexts/easeclassifieds/frontend.md for FE work).
  3. Context files contain project structure, recent fixes, configuration, and common issues.
  4. Update context files when making significant changes to keep them current.
  5. Use context files to quickly onboard new agents or understand project state.

Supervisor Context Files (supervisor-contexts/)

  1. Index: Read supervisor-contexts/CONTEXT.md first (<100 lines). It links to section files (overview, architecture, validation, usage, etc.).
  2. Section files: Read specific files as needed (e.g., validation.md, tool-contracts.md).
  3. Sliding Window: Check supervisor-contexts/windows/ for recent changes.
  4. Usage: Use when working on the supervisor system itself (not project tasks).
  5. Updates: Window files are manually maintained—do not auto-generate.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

contexts is a cursor rule published in the GitHub repository ai-supervisor-foundry/foundry (11 stars, last pushed 1mo ago), licensed MIT. It adds 5 tokens to every session and 251 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-02.
